Overview
Amazon has significantly ramped up its fight against fake reviews through its partnership with the Coalition for Trusted Reviews, a cross-industry alliance launched in 2023 that brings together major e-commerce platforms to combat review fraud globally. In 2024 alone, Amazon blocked more than 275 million suspected fake reviews and forced over 40 fake review brokers to shut down.
